INTRODUCTION: The purpose of this study was to indentify the ulnar insertion of the LUCL using the olecranon tip and the radial head as parameters to guide the ligament reconstruction surgery. METHODS: Thirteen elbows of eight fresh cadavers were dissected for the study of the LUCL. The distances between the proximal and distal insertion of the LUCL (footprint), between the radial head and the footprint and between the olecranon tip and the footprint were measure with a digital pachimeter. RESULTS: The average distance from the radial head to the proximal and distal ulnar insertion of the LUCL was 13.6 and 22.99 mm, respectively. The average distance between the olecranon tip and the proximal and distal ulnar insertion of the LUCL was 38.25 and 47.6 respectively. The mean length of the LUCL footprint was 9.35 mm. CONCLUSIONS: The LUCL insertion has a wide footprint with average 9.3 mm (7.5-11 mm). Ulnar insertion half point be located at 18.2 mm of the radial head and at 42.9 mm of olecranon tip.<br> OBJETIVO: Identificar a inser&#231;&#227;o ulnar do ligamento colateral lateral ulnar (LCLU) com o uso da ponta do ol&#233;crano e da cabe&#231;a do r&#225;dio como par&#226;metros fixos para orientar a cirurgia de reconstru&#231;&#227;o ligamentar. M&#201;TODOS: Foram dissecados 13 cotovelos de cad&#225;veres adultos frescos para estudo do LCLU. Com paqu&#237;metro digital mediram-se as dist&#226;ncias entre as inser&#231;&#245;es proximal e distal do LCLU na ulna (footprint), entre a cabe&#231;a do r&#225;dio e a zona do footprint e entre o ol&#233;crano e a zona do footprint. RESULTADOS: A dist&#226;ncia m&#233;dia da cabe&#231;a do r&#225;dio ao ponto de inser&#231;&#227;o proximal e distal do LCLU foi de 13,6 e 22,99 mm, respectivamente, da ponta do ol&#233;crano &#224; inser&#231;&#227;o proximal e distal do LCLU foi 38,25 e 47,6 mm, respectivamente, e o comprimento m&#233;dio do footprint do LCLU foi de 9,35 mm. CONCLUS&#213;ES: A inser&#231;&#227;o do LCLU tem um footprint amplo com m&#233;dia de 9,3 mm (7,5-11 mm). O ponto m&#233;dio de inser&#231;&#227;o ulnar situa-se a 18,2 mm da cabe&#231;a do r&#225;dio e a 42,9 mm da ponta do ol&#233;crano.
